Seasonic Focus GX-850 V4 ATX 3.1 Power Supply (White)

850W80 Plus GoldCybenetics PlatinumATX 3.1 / 12V-2x6
The Seasonic Focus GX-850 V4 White is the white edition of Seasonic's fully modular ATX 3.1 power supply, rated 850W with 80 Plus Gold (and Cybenetics Platinum) efficiency, built for white-themed high-end gaming PCs and workstations running PCIe 5.1 graphics cards. It carries part number FOCUS-GX-850-V4-WHITE (EAN 4711173878568) and includes a native 12V-2x6 cable that powers current-generation GPUs directly. This 2024 V4 revision adds Seasonic's OptiSink thermal design and a 135mm Digital Hybrid Fan with a true fanless mode, all in a compact 140 mm body and backed by a 10-year warranty. Typically in stock with fast delivery across Cyprus.
Compatibility & installation
Complies with ATX 3.1 and PCIe 5.1. The included native 12V-2x6 (12+4 pin, both ends) cable connects directly to current-generation GPUs — ensure both ends are fully inserted and click-locked, and do not bend the cable near the connector. OptiSink allows safe installation in any orientation. Two CPU 8/4-pin cables cover modern motherboards. Fits any case taking a standard ATX PSU at a compact 140 mm depth (140 × 150 × 86 mm). Use only the Seasonic-supplied modular cables — third-party cables can differ in pin configuration and damage your hardware even if the connector physically fits.

Best For

✓White-themed high-end gaming builds
✓Silent PCs — fanless mode + Cybenetics A- noise
✓Efficiency seekers — Cybenetics Platinum rating
✓Compact cases — 140 mm short depth, any orientation
✓Creator and workstation systems needing stable 850W
✓Long-term reliability seekers (10-year warranty)

Key Features

 
ATX 3.1 & Native 12V-2x6
Ships with a native 12V-2x6 (12+4 pin) cable for PCIe 5.1 GPUs plus three PCIe 8/6-pin cables for current-gen cards — no adapter needed.
 
Gold + Cybenetics Platinum
80 Plus Gold certified, achieving Cybenetics Platinum efficiency (90% at 50% load) for less waste heat and lower running costs.
 
OptiSink Thermal Design
A redesigned PCB with smaller MOSFETs and heatsinks gives an eightfold increase in heat dissipation, improving reliability and allowing any-orientation installation.
 
135mm Digital Hybrid Fan
A fluid-dynamic-bearing fan with three-stage Digital Hybrid control — fanless, silent and cooling modes — stays completely silent at low loads (Cybenetics A-).

Frequently Asked Questions

Does the Focus GX-850 V4 White support the latest RTX graphics cards?
Yes. It includes a native 12V-2x6 (12+4 pin) cable that connects directly to current-generation PCIe 5.1 GPUs without an adapter. Make sure both ends are fully seated and click-locked before powering on.
What is the difference between the white and black versions?
They are the same power supply — the White edition uses a white casing and white braided cables to match light-themed builds, while the standard version is black. Both are 850W, fully modular, 80 Plus Gold / Cybenetics Platinum with a 10-year warranty.
What does the Digital Hybrid Fan Control do?
It runs the 135mm fan in three stages — Fanless, Silent and Cooling. At low to moderate loads the fan stops entirely for silent operation, only spinning up when extra cooling is needed, which also extends fan life.
Is 850W enough for a high-end build?
Yes. For a single high-end GPU with a modern CPU, 850W gives comfortable headroom and keeps the PSU in its efficient, near-silent load band. It also suits demanding creator and workstation systems.
Singular Expert Insight
The Focus GX-850 V4 White brings the same excellent engineering as the black model in a clean white finish: although rated 80 Plus Gold, it achieves Cybenetics Platinum efficiency, runs truly fanless at low loads, and adds the new OptiSink thermal design — all with a 10-year warranty in a compact 140 mm body. It is an ideal all-round choice for a light-themed high-end single-GPU build. If your system draws less, the 750W model saves money, while the 1000W suits more demanding rigs.

Buyer's Guide

Buy it if
You want a quiet, high-efficiency white 850W ATX 3.1 PSU from a top-tier brand with a native 12V-2x6 cable and a 10-year warranty.
Skip it if
You prefer a black PSU, or your build draws well under ~550W — a smaller unit will run nearer its sweet spot for less.
Also consider
The Focus GX-750 V4 for lighter builds, the GX-1000 V4 for more headroom, or the black GX-850 V4.
